SYSLINK: ipc - Add SysMgr & SysMemMgr

This patch adds the preliminary source code for SysMgr & SysMemMgr.
This patch includes only the source code and needs revisions to
adapt to the latest loader and OMAP4430.

The patch has one checkpatch warnings due to the usage of volatile keyword.
The warnings were minimized by using a macro for volatile.
